[Enhancement] Improve JavaDoc and Code Comments

[psxjoy]

Descript

Some functions in Fastexcel currently lack proper JavaDoc or inline comments, which may make them more difficult for newcomers to understand.

Goal:

Add well-structured JavaDoc and comments to core functions to enhance code readability and usability.

This represents an ongoing, long-term initiative aimed at eradicating typos and enhancing the project's readability.
IMO, initiating this effort by correcting typos or annotating certain functions serves as an excellent starting point.

Every PR that aids in enhancing the project deserves encouragement :)

May I ask if there is any specific function list that requires writing a comment document? I didn't know where to start when it came to participating in an open source project for the first time.

IMO, annotating test cases is an excellent approach for those new to the project.
There's no need to worry excessively about making mistakes or submitting PRs that may not be perfect;
we appreciate all efforts directed towards enhancing the project.
